ROLLERQBEARING.

Specification of Letters'Patent. I

To all whom it may concern Be it known that I, J ULIUS 'BRENZINGER,'3. citizen' of "the United States, residing at Mount Vernon, in the county of WVestchester and State of New York, have invented certain new and useful Improvements in Roller Bearings, of which the following is a specification.

This invention relates to roller-bearings, with more particular reference to that class of bearings in which a plurality of cylindrical metal tubes are revolubly mounted on the tubes or rollers are free metal pins "which are supported at their ends by annular head or endpieces, said head or end pieces being held in some manner in proper relation to each other so that to revolve on their respective pins.

The principal objects of the presentin vention include the provision of a rollerbearing the parts of which may be assembled easily and quickly, and in which'the case hardening of the wearing parts of the bearing may besimplified; also the provision of a roller-bearing which will be extremely simple, very light in proportion to its strength, readily adaptable to various uses and susceptible of being manufactured rapidly and cheaply.

Still further objects and advantages of the present invention will be apparent to those skilled in this art, and will readily be understood from the following specification and claims and the annexed drawing, in which Figure 1 is a top plan View of a roller i bearing embodying my invention; Fig.2 is

' and a top plan view of the same, with the outermost member of the double end or head piece removed; Fig. 3 is a vertical section taken substantially on line ofrFig. 1,

Fig. 4 is a vertical sect on taken substantially on line YY of Fig. 1.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures ofv the drawmg.

Referring now to the drawingin detail, numeral 11 indicates a cylindrical tube of steel or other suitable metal, there being a plurality of these tubes of exactly similar shape and dimensions employed in each bearing, and nine of these tubes being shown ing drawing.

other suitable metal which solid'but may be tubular if circular in cross-section and the diameter of which is somewhat less than the interior diameter of the tubes or rollers 11. In con? nection with a bearing embodying my invention in which nine rollers are employed, six of the pins upon which said rollers are mounted are exactly similar and have the same functions, said pins being of uniform diameterthroughout and being cut off at both ends substantially at rightrangles to their longitudinal center lines. Pins 13 are longer than pins l2and are provided at each end with a substantially square shoulder and an extension which is smaller in diameter than'the pin itself and is preferably cir-' cular in cross-section, the main or body portions of pins 13 being of thesame diameter as pins 12, so that rollers 11 fit pins 13, as well as on pins 12, luble thereon. Manifestly'the bers of pins 12 and pins 13 used. in a bearing embodying is. preferably preferred, is

and are revorelative numwhich may be mV invention the smaller sizes. I have found it desirable to employ three'jof the pins 13.

Each of the two head or end pieces 1a and 15 in which the pins 12 and 13 are mounted consists of two the form of a washer or ring, It has been my practice in the construction of bearings embodying my invention to make the inner head or end piece 14 somewhatthicker than the outer head or end piece'15, andyboth are punched or otherwise formed from sheet steel-or other suitable metal. At equal intervals around ring 1 1, so as to be arranged symmetrically, and, located on the center line of the circumferential face of the ring, are punched or otherwise formed the nine circular openings 16'of slightly larger diameter than that of the pins 12 and 13, so that said pins will 'fit closely insaid openings but the fit will not be so tight as to necessitate the expenditure of force in putting the pins into place. The-outer ring 15 has openings 17 punched or otherwise formed therein. said openings being spaced uniformly and located on the center line of the circumferenin the bearing illustrated by the accompany- 7 Numeral 12 indicates a pin of steel or loosely on.

pins are arranged tial face of the ring, and being of such shape and dimensionsasto adapt them to receive the reduced extensions of pins 13,

the tightness of the fit being substantially the same as that ofpins 12 in openings 16..

In assembling one of my improved roller bearings, it is my practice to proceed as in the accompanying drawing, sothat each pin may pro]ect beyond its roller 'at each end of the latter similarly each of the pins 13has a roller mounted thereon, thelength' of the body portion of each ofsaid pins being substantially the same asthat of pins 12. The projectingends ofv pinslQ and'jl3 are then inserted into the, openings'l6. in rings 14, in such order that the rollers and symmetrically around said rings, and therings-le are adjusted in such positions relativeto eachother that their faces are substantially parallel, the

v ends of pins'lQ are substantially'flush with CAv the outer facesof rings-14 andlthereduced extensions of pins 13' pro'jectbeyond, the outerfaces of both ofthe rings 14L. Rings 15 are next put into place by fitting the 7 openings 17' over the reducedextensions of pins 13 and pressing rings 15 tightly into contact with rings 14. Having thus assembled: the parts in the desiredpositions, the manufacture of the bearingis completed by upsetting the ends of the reduced extensions of pins 13 which project beyond the outer faces of rings 15.

' It is manifestly desirable inassembling my improved roller bearings in the manner just described, or otherwise, to lubricate the pins 12 and 13 either prior, to mounting the rollers 11 thereon or subsequently thereto; it is also manifestly desirable in assembling the parts to so adjust the positions of the end or head pieces (each comprising a ring 14 and a ring 15) relative to each other that a slight clearance shall be left between the ends of rollers 11 and the inner rings le ofthe end or head pieces, thus leaving I the rollers 11 free to turn with a minimum of friction on pins 12.

In getting the parts of'my improved bearings ready for assembling, it is my practice to case harden rollers 11, pins 12 and rings 14, but it is'not my practice to harden pins 13 or rings 10, since it is manifestly unnecessary to harden rings 15 and although it would be possible to harden the body portions of pins 13, leaving the reduced eX- tensicns of said pins sufliciently soft so that they may be upset or riveted, I have not found it necessary to harden pins 13'especially in the case of bearings which areof relatively small size and intended for relativelylight service.

It will be apparent from the foregoing "description of my-improvedroller-bearing, v and of the manner in which the partsf are adapted to be assembled, that all; of; the

pa'rt'sim'ay be manufactured rapidly and cheaply by automatic machinery or otherwise, all of the wearing parts may lbe'CaSp hardened. in a very simple and inexpensive;

Many modifications of minor detailsof' my improved roller-bearing will doubtless readily suggest themselves to those skilled in this art, andEI therefore donotdesirecto limit my invention to the specific, construc: tion herein shown and described,
